signs

The good news? Falling in love again is possible.
While I can't read her mind, I know that my cat is also constantly finding new ways to tell me she loves me. And just as there are specific behaviors through which a dog communicates love, there are specific, unique ways that our cats are saying "I love you."
So long as you haven't agreed to any limitations on the appearance of your home (such as through a Homeowners Association or deed restriction), you're free to put up any signs you want, regardless of how violent, offensive, or profane they may be to others.
Documenting these things was just a way to remember them before they disappeared forever.
